 Add AI for new moves/items/abilities.
 
-Code for the form differences:
-- Cramorant (in battle only)
-- Toxel/Toxtricity (depends on nature)
-- Sinistea/Polteageist (form 1 is rare and not inheritable by breeding)
-- Milcery (depends on held item and random number)
-- Alcremie (random)
-- Eiscue (in battle only)
-- Indeedee (gender)
-- Morpeko (in battle only)
-- Zacian
-- Zamazenta
-- Kubfu (no code needed; form is manually set just before evolution)
-- Urshifu
-- Calyrex (fising, learns move upon fusion/defusion)
-- Galarian forms (make sure breeding inherits them)(Koffing and Mime Jr. are the
-  same)

-I think there are some alternate forms which don't have a hidden ability while
-their base forms do. I don't think the compiler supports this, and instead
-treats Abilities and HiddenAbilities separately. Can work around this by setting
-HiddenAbilities to be the same as Abilities. I'm not too happy with this.
+Zacian/Zamazenta need code that changes their movesets upon entering/leaving
+battle. Can't use "onSetForm" since that's called after the battler is
+initialized and pbOnEnteringBattle doesn't have access to the battler (could
+change this).
